A cramped position or difficulty turning can prompt a size check, but litter scatter, a tail over the edge or avoiding the tray does not by itself prove that the tray is too small. Review fit alongside health, access and the rest of the toileting setup.
Do not wait to address urinary difficulty
If your cat is straining and passing little or no urine, contact a vet immediately. A blocked bladder is an emergency. Cats Protection’s urinary-problems guidance explains the warning signs. New toileting changes should not be managed solely by buying a bigger tray and waiting to see what happens.
Observe the available room
- Can your cat enter and leave without squeezing or struggling?
- Is there room to turn and adopt its usual toileting position?
- Does a hood or door restrict headroom or access?
- Is the step-over height manageable?
Compare these observations with usable interior dimensions. The external shell and the tail’s position are not substitutes for measuring the litter area.
Measure body length
Catsan recommends a tray around one and a half times the length from nose to the base of the tail. Use this as a starting point, together with your cat’s movement and preferences. Our tray-size label guide explains which measurements to compare.
Review the setup too
Location, cleanliness, litter choice and access around other cats can also affect use. Seek veterinary advice about new changes rather than assuming a size problem. When comparing the tray range, ask for any missing interior or entrance measurements before ordering.
